EFF Decrypts Laser Printer Codes

The Electronic Frontier Foundation has published information about tracking codes printed in every document by laser printers from Xerox, Canon, Brother, Dell, Epson and other companies. These codes, which have been decrypted for one model of Xerox printer, indicate the date and time the document was printed and the serial number of the printer. The codes have apparently been in effect for at least a decade.
